Vacant city lots and buildings are often used as starting points for cultural innovations. Over the course of the transformation of the postindustrial city, public space has become an exciting laboratory for interdisciplinary cooperation between artists, architects, urban planners, and landscape architects. Featuring essays by acknowledged experts, Back to the City documents twenty-eight site-specific installations and temporary interventions in Germany and Australia that provide perspectives for the revitalization of fallow land, thus demonstrating the potential of the temporary use of urban space. The projects date from 2002 to 2008 and were curated by architect and urban planner Steffen Lehmann, Professor at the University of Newcastle, Australia, UNESCO Professor of Sustainable Urban Development, and the founding director of s_Lab Space Laboratory for Architectural Research and Design.
